IMPROVEMENT IN CA R-COUPLINGS.

Specification forming part of Letters Patent N 0. 218,466, dated AugustI2, 1879; application filed May 13, 1879.

ings, and to letters ofreference marked thereon,

which form a part of this specification.

My invention relates to safety-couplings for railroad-cars; and itconsists of devices for operating the ordinary link-and-pin couplings,

so that the operator may not be exposed to danger between the cars,which devices are constructed as hereinafter described, and as shown inthe drawings, in which Figure l is a plan view of the draw-heads andcouplings of two cars to be coupled. Figs. 2 and 3 are end views of thesame. Fig. 4 is a side view of one of the draw-heads with the couplingdevices. Figs. 5 and 6 are views of the link and pin supportersdetached.

A A represent the draw-heads of two cars to be coupled. B represents alink-supporter adjusted to slide in a slot in the draw-head, andprovided with lugs b b to hold the link B in'position laterally, andhaving a slot, 1), to receive the end of the couplingpin, a plate, 0,forming a stop to the inner end of the link, and the pins cc to receivethe inner end of the operating-lever.

0 represents the coupling pin supporter adjusted to slide in the slot inthe draw-head. This supporter is bifurcated, forming the arms at d,which are adjusted to slide in grooves in the sides of the draw-head,and it is provided with the pins d d to receive the inner end of theoperating-lever.

The coupling-pin G is operated by a lever, D, pivoted to a standard, E;and the linksupporter and pin-supporter are operated by the side levers,D E, pivoted at a, the inner ends of which levers extend in between thepins on the supporter-plates; and the outer ends of all the leversextend outward far enough to enable the operator to couple and uncouplethe cars without going in between them.

In coupling the cars the link-supporter oi the draw-head containing thelink is moved out by lever D, as shown in Fig. 1; and the link-supporterof the other draw-headis moved back by its side lever, and the pin iselevated by the lever D, and the pin-supporter moved outward by thelever E, as shown in Figs. 1 and 2 of the drawings. In this position theends of the arms d extend beyond the end or the draw-head, and the linkis held in a horizontal position; and as the cars are moved together theextended end of the link enters the other draw-head, and the end of thedrawhead A, striking the ends of the arms (1, slides back the supporter0 from under the couplingpin, which drops through the link coupling thecars.

What I claim as new, and desire to secure by Letters Patent, is-

1. The link-supporterB, having the lugs b b and stop-plate c, andadjusted to slide in the draw-head by means of the side lever, D,substantially as and for the purposes described.

2. The coupling-pin supporter consisting or the plate 0, having theprojecting arms d d, in combination with the operating-lever E, wherebythe plate may be moved back and forth in the draw-head, substantially asand for the purposes described.

In testimony that I claim the foregoing as my own invention I affix mysignature in presence of two witnesses.

EDWARD M. WILLIAMS.
